Stem and leaf plot

A stem and leaf plot is a numerical display of the distribution of a variable. The information is written to show that the last digit is the leaf and the rest of the numbers in front are the stem. The one above is just an example on how stem and leaf plots work. http://www.webquest.hawaii.edu/kahihi/mathdictionary/images/stem_leaf_graph1.gif

Histogram

A histogram is a diagram consisting of individual bars who has different values. The values are dependent on the y-axis and the x-axis. The y-axis determines how high the bars will rise, while the x-axis is what we are measuring. The map shows the hours of delay in traffic per major city. http://www.coolinfographics.com/blog/2010/2/9/city-population-shift-maps.html

nominal area choropleth map

A nominal area choropleth map is a thematic map that displays areal data. These maps use different colors or patterns to distinguish between certain areas or regions. The data that is represented is nominal data, meaning there is no ranking order for each category, so therefore a rainbow of different colors is many times used.
